Abstract
Understanding how quarks and gluons behave in the nuclear environment is an important focus of modern nuclear physics. Recent measurements have provided an improved understanding of how quark and gluon densities are altered in heavy nuclei. It has also become possible to make multi-dimensional pictures of the nucleus, exploring how these alterations are distributed within heavy nuclei. The modifications are naturally expected to be largest in the core of a nucleus and smaller near its periphery; this variation can change the effective shape of the nucleus. Experiments have also started to explore the transverse momentum distribution of the partons in the nuclei, and, by using incoherent photoproduction as a probe, measure event-by-event fluctuations in nucleon and nuclei parton densities. This Review explores recent progress in measurements of nuclear structure at high energy, emphasizing these multi-dimensional pictures. We also discuss how a future electron–ion collider with high luminosity and centre-of-mass energy will make exquisitely detailed images of partons in a nucleus.
